VG7441ST+3008E Johnson Controls Valve / Actuator

Overview

The Johnson Controls VG7441ST+3008E is a 2-inch, 2-way globe valve assembly equipped with a V-3000 series pneumatic actuator. Featuring a cast bronze body and a durable brass trim, this compact, exposed-yoke control valve is engineered to regulate the flow of water and steam in commercial HVAC installations. It functions in a spring-return, normally-closed configuration, ensuring fail-safe shutdown when air pressure is lost.

Features

• Compact design with an exposed yoke for easier serviceability and maintenance.
• Robust cast bronze body providing enhanced strength and long-term durability.
• Brass trim construction featuring a secure elastomer disc seat for reliable closing performance.
• Dependable spring-return mechanism configured to remain normally closed upon signal loss.
• High flow capacity offering a maximum rating of 46.2 Cv to handle standard commercial system demands.
